RESOLUTION NO.2026-01
A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF DIAMOND
BAR, CALIFORNIA, RECOMMENDING THAT THE CITY COUNCIL CERTIFY THE
FINAL SUPPLEMENTAL ENVIRONMENTAL IMPACT REPORT (SCH NO.
2018061066), ADOPT FINDINGS OF FACT AND A STATEMENT OF OVERRIDING
CONSIDERATIONS, AND APPROVE THE MITIGATION MONITORING AND
REPORTING PROGRAM FOR THE TOWN CENTER SPECIFIC PLAN.
A. RECITALS
1. On December 17, 2019, the City Council adopted the Diamond Bar General
Plan 2040 ("General Plan") and the Climate Action Plan 2040 ("CAP") to
create a vision and blueprint for development through 2040. The Diamond
Bar General Plan 2040 establishes the Town Center Mixed -Use,
Neighborhood Mixed -Use, Transit Oriented Mixed -Use, and Community
Core Overlay focus areas and corresponding land use designations,
estimates that up to 3,750 new housing units could be built in the city by
2040, and anticipates that much of this growth will occur within these four
focus areas.
2. On August 11, 2022, the City Council adopted the City's 2021-2029 General
Plan Housing Element ("2021-2029 Housing Element" or "6th Cycle Housing
Element"), which was subsequently found by the California Department of
Housing and Community Development (HCD) to be in full compliance with
State Housing Element Law (Article 10.6 of the Gov. Code) on October 5,
2022. The 2021-2029 Housing Element identifies sites to accommodate the
City's Regional Housing Needs Allocation (RHNA) of 2,516 residential units,
including through rezoning of underutilized sites in the Town Center Mixed -
Use, Neighborhood Mixed -Use, Transit Oriented Mixed -Use focus areas to
allow residential development at a minimum density of 20 dwelling units per
acre and a maximum density of at least 30 dwelling units per acre.
3. In conjunction with the adoption of the General Plan and the CAP, the City,
as lead agency, prepared an Environmental Impact Report, State
Clearinghouse Number 2018051066, to analyze the potential
environmental impacts of those plans (the "EIR"). The City Council certified
the EIR on December 17, 2019, and the City filed a Notice of Determination
on December 18, 2019. In conjunction with the adoption of the 2021-2029
Housing Element, the City, as lead agency, evaluated the potential
environmental impacts of the Housing Element in an addendum to the EIR,
and the City Council adopted the addendum on August 11, 2022.
4. On January 27, 2025, the City Council adopted Resolution No. 2025-04
approving an amendment to the Land Use Element of the General Plan to
establish a minimum residential density of 20 dwelling units per acre and a
maximum residential density of 30 dwelling units per acre on sites within the
Town Center Mixed -Use and Neighborhood Mixed -Use Land Use
Designations.
5. On February 4, 2025, the City Council adopted Ordinance No. 01 (2025),
establishing the housing element site (H) overlay district to provide
development and land use regulations for the development of multifamily
dwellings on specified sites identified in the City of Diamond Bar 2021-2029
Housing Element to accommodate the City's RHNA requirements. The
Zoning Map was concurrently amended to apply the H overlay district
designation to those parcels with a General Plan land use designation of
Town Center Mixed -Use, Neighborhood Mixed -Use, and Transit -Oriented
Mixed -Use. The H overlay district establishes a maximum residential
density of 30 dwelling units per acre. Because the H overlay district
implements the densities established in the General Plan Land Use Element
and required by the 2021-2029 Housing Element for the Town Center
Mixed -Use, Neighborhood Mixed -Use, Transit Oriented Mixed -Use focus
areas, the City Council determined that the rezoning of the specified sites
would not result in any new significant impacts or a substantial increase in
the severity of previously identified significant impacts; therefore, no further
environmental analysis was required. (Public Resources Code § 21166;
CEQA Guidelines §§ 15168, 15162.)
6. The Town Center Mixed Use land use designation ("Town Center" or
"Planning Area") consists of approximately 45 acres, bounded on the north
by the Pomona Freeway (State Route [SR] 60), on the east by a
neighborhood of single-family homes, on the south by Lorbeer Middle
School and Mount Calvary Lutheran Church and School, and on the west
by the Fall Creek private condominium community. The Planning Area is
composed of 35 individual parcels with 23 unique property owners within a
suburban -style commercial district. The Planning Area is centered around
Diamond Bar Boulevard, a six -lane thoroughfare with painted bike lanes,
that bisects the Town Center and extends over 1,800 feet. It is bounded on
the south by Golden Springs Drive for approximately 1,600 feet and on the
north by the SR-60 Freeway. Access to the Town Center is provided by both
SR-60 and SR-57. Travelling on SR-60, access to the Town Center can be
attained by Diamond Bar Boulevard (Exit 26).
7. The Land Use and Economic Development Element the General Plan
established the Town Center Mixed -Use land use designation to transform
a suburban style, auto -oriented neighborhood commercial area .into a
"vibrant, pedestrian -oriented Town Center in Diamond Bar" to "encourage a
mix of uses with an emphasis on community -serving and destination retail,
2
dining, and entertainment uses, in addition to offices, professional services,
and residential uses.
8. In July 2022, the City initiated preparation of the Town Center Specific Plan
("TCSP") to implement the vision, goals and policies set forth in the General
Plan, as well as the recommended land use strategies published in the
Urban Land Institute -Los Angeles ("ULI-LA") Technical Assistance Panel
("TAP") Report, published in April 2021. One of the TAP Report's key
recommendations was to accommodate a residential buildout of more than
2,000 dwellings units in the Town Center, or approximately 700 more
dwelling units than what a base density of 30 dwelling units per acre would
yield under the current General Plan and zoning designations.
9. The TCSP will establish a regulatory framework to guide the transformation
of the Town Center from the existing suburban -style retail shopping centers
into a pedestrian -oriented downtown, providing housing opportunities,
retail, restaurants, and entertainment uses within the City of Diamond Bar.
Implementation of the TCSP is anticipated to result in the development of
up to 2,055 housing units (an increase of 705 units); 200 hotel rooms (an
increase of 103 rooms); 40,000 square feet of public open space (an
increase of 40,000 square feet); and 446,000 square feet of commercial
space (a net decrease of 64,000 square feet), including retail, dining, and
entertainment uses, as compared to development anticipated for the area
under the General Plan, as amended by the 2021-2029 Housing Element.
This proposed increase in density is consistent with the major conclusions
TAP report, which found that higher residential densities are appropriate for
achieving a viable, mixed -use Town Center. Supporting infrastructure and
development standards will be implemented through the TCSP and
associated entitlements.
10. Approval and implementation of the TCSP requires City Council adoption
of concurrent legislative actions, including a General Plan amendment and
an ordinance to amend the Official Zoning Map and Title 22 of the Diamond
Bar City Code ("Development Code") to establish the TCSP as the
regulatory document governing the Town Center. These actions would
revise the General Plan criteria and the zoning designation applicable to the
Planning Area as necessary to ensure consistency with, and
implementation of, the TCSP's framework, including maximum residential
density and permitted uses. The General Plan Amendment, TCSP, and
amendments to the Official Zoning Map and the Development Code
collectively constitute the "Project."
11. The City of Diamond Bar ("City") is the Lead Agency for the Project, as
defined by Section 21067 of the California Environmental Quality Act
("CEQA") Statutes (Public Resources Code Section 21000 et seq.).
3
12. The City determined that the appropriate environmental document for the
Project would be a Supplemental Environmental Impact Report ("SIR") to
the certified General Plan and CAP Program EIR ("Certified EIR"), as
addended on August 11, 2022 with adoption of the 2021-2029 Housing
Element Update
13. On June 5, 2023, the City disseminated a Notice of Preparation ("NOP") to
solicit comments on the scope and content of the SIR. The NOP was sent

Area; and emailed to individuals who subscribed to receive TCSP
notifications. The NOP was circulated for a 30-day review period that
commenced on June 5, 2023, and ended on July 5, 2013.
14. On June 8, 2023, as part of the scoping process, a Scoping meeting was
held at Diamond Bar City Hall, 21810 Copley Drive, Diamond Bar,
California, during which 30 verbal comments were received and
incorporated where appropriate into the Draft SIR.
